Be it known that I, THoMAs a ycitizen of theA United States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have" invented certain new and useful vlmpr'ovements in V Locking Devicesfor Automobiles,`ofwhich the following is aspecification.v .Y

My present inventionV relates to locking devices and particularly to devices for locking Vthe levers, such'for example as the footoperated levers of automobiles to` preventA` an unauthorized person from actuating the levers so that the automobile can-not be operated when the 'parts are theirlocked` positions. Furthermore my present inven-` tion relates to the same'general ty'fpe of 'de- Vice Adisclosed in 'my co-pending- United VStates application for patent, Serial No.' A452555,51@ March 17,1921. Y

One objectV of the *device* of my present invention is to provide locking'means which" can be movedby resilient means into kppsitiveV locking position. nl' i Another object is to so constructmy iin'-A proved device that it can be readily attached to automobiles of various types in which the operating levers have different arrange i ments and as such is adaptedwlthout change to permit lthe ready attachment to levers which are spaced.,y at Y different distances A still further object is to make my improved device o'fa durable'const'ruction and so that it can be easily and cheaply manufactured. r v i v These objects, 'and other advantageous ends which will be described hereinafter, I

attain in the following.manner,xreference being had which- A l Y v Figure 1Y is a top plan view showing my" improved device attached to the floor of anv automobile,

. Referring to the drawings,- 12 represents a portion of the floor of anjautomobile and to the undersurfacc of the floorv 12 is 'sen cured a housing 13Whichis preferably made ofinetal and includes a main channel section' lwhichjhas an upright` hollow boss 15 .which projects through ahole 16 inthe oor12; A tubularstandardv 17 fits within, the'boss 15 andatits top` includes a cap 18 having'partitions 19 spaced apart; said pan.

l which the'lower`rend of thepost '23 fits so that it willbe understood that whenthe key 21 is inserted through the cap 1S said keyl can beused as a levermfor rotating the post 23, and' the actuating member 29 will also' be rotated.` j Y Y p I The housing 13 includes a lower channel sectionV 31 zwhich-'has upwardly ,extending portions 31a providing transversely extend-L ing guideways and 33 asy shown` in vF igurejs 3 ando. vIn similar manner the section 31` has" upwardlyl extending-' .portions 34,'

which Vprovides a guideway 35 extending in the direction `of the length` of the device Y. substantially at fright angles to the guideways'32V and 33,; said guideways 32 and 33 being located at opposite sides of the guidefV way 35.'11Locking2bars 36. land 37' are fslid "abl'y mounted within the 'guidewayisaid loclring bars having teeth 38 and 39v on` opposite edgesgsaidteeth 'beingoppo'sed re-V spectivelyto the guideways 32 and 33.' Bolts Y' 10 and .41 are slidably mounted in the guide Y ways 32' and 33. lThe 'outer'ends of the guideways 32 and 33 are closed by tongues 42 which depend fromy the channel section 14. Springs 43 bear against the tongues 42 and lit within recesses inthe bolts 41 asshown in Figure 4; said springs being operative to move the bolts 41 toward each other;

the channelsection 14. The surface 46 of;

the actuating member 29 has opposed de pressions 47A and other opposed depressions 48; the portions of the surface 46 providing the depressions 47 being closer to .the aXis of rotation than are the portions of the surface 46 Vwhich provides the depressions 48. lt will be noted'that the springs 43 serve to move the rollers45 into and keep Y them in Contact withthe surface 46 of the actuating member 29. When the depressions 47 arel in line with the rollers 45, the springs 43 can move the bolts 41 with the ribs 44 in meshwith the teeth of the respective locking bars 36 and 37. However, when the actuating member 29 is turned to bring the depressions v48 in line with" the Y rangedY groups of notches 50 in their uppersurfaces as shown inFigurev2; said arms also having holes 5l which extend upwardly therethrough and communicate at their tops with the respective notches 50. rllhese notches and holes of the arms 49 are arranged'at spaced distances apart within the width Vof the device and serve as connecting means for links 52 and 53 which links may bey lattached in anyy suitable manner to the actuating levers of the automobile; said links 52 'and 5,8itting within thenotches 5() most suitable for them according to the spacing of the levers on the automobile. The links 52 and 53 have downwardly extending hooked portions 54 which lit within the holes 51so as to longitudinally lock or secure the linksy to the locking bars. Guiding pins 5 5 depend from the, channel section 14 at spaced distances apart in a straight row and serve as spacing and 'guiding means for the locking bars 3.6 and 37.

@n the operati n of the rdevice when itis desired to lock the levers of the vehicle, the key 21 is rotated a quarter turn and removed; this action bringing the depressions 47 in alignment with the rollers 45 so that the springs 43 will move the bolts 41 toward the bars 36 and 37. Even though no one of the notches between the teeth of the locking bars is directly in line with the ribs 45, it is obvious that any attempt to move the levers will move the teeth into alignment with the ribs 44 of the bolts 41 and the springs 43 willthen push the bolts so that the ribs 44 will snugly enter the notches between the teeth inthe locking bars and prevent' further movement of the locking bars. Thus by having the bolts movable into locking engagement by the springs a direct lockingl engagement between the bolts and the locking bars can also be secured even though the notches between the teeth of the locking bars are not in direct alignment with the ribs of the bolts 41 when the key is turned.

When it is desired to unlock the device the key 21 is inserted and turned a quarter turn during which action the portions of the sur# face 46 of the actuating member 29 will opcrate uponithe rollers 45 to withdraw the bolts from locking engagement with the locking bars and when the depressions 48 become in alignment with the rollers 45, the springs48 will act to move the rollers 45 into the depressions 48 and thereby hold the actuating member 29 against accidental rotatable movement. However., the movement of the rollers 45 into the depressions 48 is not suiiicient to permit the ribs 44 to enter the notches between the teeth of the locking bars.

While l have described my invention as takinga particular form, it will be under# stood that vthe various parts of my Yinvention may be changed without departing from t-he spirit thereof, and hence l do not limit myself to the precise lconstruction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what l claim as new and desire to secure bylietters Patent .is o
